, multi-link suspension is a typical representative of independent suspension
suspension components is simple, but the determination of parameters is quite complex, manufacturers must not only consider car comfort, handling stability also take into account the cost issues. Based on three different manufacturers have different preference strategies. Also produced the more common of the five suspension: McPherson independent suspension, double-wishbone independent suspension, a single trailing arm torsion beam semi-independent suspension, rod strut independent suspension, multi-link independent suspension.
suspension frame with elastic wheels linked and related to a variety of performance car is one of the car the three most important assembly (the other two are: the engine and gearbox). From a structural point of view, the automotive suspension only simple components by the number of rod, tube and spring, but the car suspension is a very difficult to achieve the perfect requirements of automotive assembly, this is because the suspension is necessary to meet the vehicle handling and stability requirements, but also to ensure the car's comfort requirements, both of which are mutually contradictory. In order to achieve good comfort significantly buffer the car vibration World pipe network reported that the world's steel pipe network to provide the world's steel pipe network editor , so spring must be designed to be softer, but the soft spring but it is easier the car brake "nod" to accelerate the "heard" as well as a serious roll bias in favor of auto turn, likely to cause vehicle handling instability.

● suspension hanging in the vehicle chassis placement diagram
First of all, let us look at what is hanging: suspension a car frame and axle or wheel all power transmission between the general term for the connected device, the suspension's main role is to pass between the wheels and the body force and moment, such as the support force, braking force and driving force, and ease the load of the impact of body passed by the uneven road, the attenuation caused by vibration, and occupant comfort, reduce the dynamic load of cargo and vehicles. Typical vehicle suspension structure by the composition of the elastic components, shock absorbers and oriented institutions, the three parts from the role of buffer, damping and power transfer. The vast majority of suspension with coil springs and shock absorber structure and more, but different types of suspension-oriented institutions difference is great, and this is the hoisting of the core components of the performance difference. According to the structure can be divided into non-independent suspension and independent suspension two.
"before and after are used independent suspension
in this theory will say the era of the movement, almost all car brands and more vigorously promote their products excellent handling performance from the Europe Department of the BMW, Audi, Saab, Acura to the Japanese, the British Infiniti and other high-end brands are all struggling to promote their good handling and movement, and even the Mercedes-Benz, Cadillac, Lexus and other high-end brand has always been a comfortable performance-oriented design also recently added more movement orientation. The luxury cars from compact cars to Fox MAGOTAN Chevrolet to the BMW 5 Series Li all flaunt their athletic performance World Steel Pipe News .
non-independent suspension is a bar directly rigidly connected to both sides of the wheel on the side of the wheel by shock, vibration is bound to affect the other side of the wheel, so naturally does not get better handling stability and comfort, while the mutual influence of the right and left wheels, it tends to affect the stability of the body, in turn, are more prone to The rollover occurred. Independent suspension, solid chassis is very obvious. As a result of the independent suspension on both sides of the car's wheels independently of each other connected to the body, use the process from the point of view, when the side of the wheel impact, vibration through the elastic element can absorb the impact, this impact is not spread to another side of the wheels so that manufacturers can be the beginning of the design of the model through the appropriate adjustment to the car in comfort, stability, handling and stability in three areas to obtain a reasonable configuration. The selection of independent suspension car general handling and comfort were significantly better than the selection of non-independent suspension car.
